The machine .config file specifies the settings that are global to a particular machine - so whatever you changed can potentially affect every other app on the machine.

The App config contains application specific settings so your applications settings really should be in there.

When you built and deployed your application to Program Files was the app config copied along with it? Did you set the "Copy to Output Directory" property?
